* autoboot: remove CONFIG_ZERO_BOOTDELAY_CHECKMasahiro Yamada2016-07-01-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the help message of CONFIG_BOOTDELAY says, CONFIG_BOOTDELAY=-2 means the autoboot with no delay, with no abort check even if CONFIG_ZERO_BOOTDELAY_CHECK is defined. To sum up, the autoboot behaves as follows: [1] CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=y autoboot with no delay, but you can abort it by key input [2] CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=n autoboot with no delay, with no check for abort [3] CONFIG_BOOTDELAY=-1 disable autoboot [4] CONFIG_BOOTDELAY=-2 autoboot with no delay, with no check for abort As you notice, [2] and [4] come to the same result, which means we do not need CONFIG_ZERO_BOOTDELAY_CHECK. We can control all the cases only by CONFIG_BOOTDELAY, like this: [1] CONFIG_BOOTDELAY=0 autoboot with no delay, but you can abort it by key input [2] CONFIG_BOOTDELAY=-1 disable autoboot [3] CONFIG_BOOTDELAY=-2 autoboot with no delay, with no check for abort This commit converts the logic as follow: CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=n --> CONFIG_BOOTDELAY=-2 Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Stefan Roese <sr@denx.de> Acked-by: Igor Grinberg <grinberg@compulab.co.il> Reviewed-by: Simon Glass <sjg@chromium.org> Acked-by: Vladimir Zapolskiy <vz@mleia.com> Reviewed-by: Heiko Schocher <hs@denx.de> Acked-by: Christian Riesch <christian.riesch@omicronenergy.com> Acked-by: Hannes Schmelzer <hannes.schmelzer@br-automation.com>

| | | | | | | | | | | The description was borrowed from kernel. Definitions were added to defconfig files in a way that "make savedefconfig" generates exactly the same file as used defconfig.

| | | | | | | | | | | | | | The description was borrowed from kernel. "tristate" type was changed to "bool" (I believe we don't support modules for u-boot yet, right?).

* kconfig: add config option for shell promptNikita Kiryanov2015-08-13-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add option to set shell prompt string from menuconfig and migrate boards globally. The migration is done as follows: - Boards that explicitly and unconditionally set CONFIG_SYS_PROMPT had the entry moved to their defconfig files. - Boards that defined some kind of #ifdef logic which selects the CONFIG_SYS_PROMPT (for example qemu-mips) got an #undef CONFIG_SYS_PROMPT right before the #ifdef logic and were left alone. - This change forces CONFIG_SYS_PROMPT to be a per board decision, and thus CONFIG_SYS_PROMPT was removed from all <soc>_common.h and <arch>_common.h files. This results in a streamlined default value across platforms, and includes the following files: spear-common, sunxi-common, mv-common, ti_armv7_common, tegra-common, at91-sama5_common, and zynq-common. - Boards that relied on <arch/soc>_common.h values of CONFIG_SYS_PROMPT were not updated in their respective defconfig files under the assumption that since they did not explicitly define a value, they're fine with whatever the default is. - On the other hand, boards that relied on a value defined in some <boards>_common.h file such as woodburn_common, rpi-common, bur_am335x_common, ls2085a_common, siemens_am33x_common, and omap3_evm_common, had their values moved to the respective defconfig files. - The define V_PROMPT was removed, since it is not used anywhere except for assigning a value for CONFIG_SYS_PROMPT.
